Guys, I need your help again.
You probably remember the AK4396 board we designed in our combined effort a few years back.
Well I did a mistake reading the schematic and the layout endet up being the serial mode one.
In the past I just cut some traces and lifted one leg of the AK4396 and all was fine but now
I want to use it for a multi-channel digital crossover via an Envy24HT based soundcard.
Pages 27-30 in the datasheet talks about addresses and registers and D7-D0
but how in the world do I get to them?
Is there a way to program the dac with a PC or just a few switches?
All I need to do is set the format to I2S input, soft roll off, and double speed for my 24.576mhz clock.
The clock will stay fixed as I use an AD1896 SRC to feed the dac.
Because I use the PC for the crossover anyway would it be possible to send the data via it? Maybe over the com port?
There seems to be only 3 wires needed for this task. The dac itself is about two feed away from the PC.
As I use LVDS for all I2S lines I got a few wires left from the twisted pair bundle for this task.
Any help is greatly appreciated. I am just a poor boy...... but for dedicated help.....I got lots of good AK4396 dac boards
designed by professionals...... only for serial mode of course....

Greets,
Klaus

Please Guys,
gimme one examle code or line that shows me how to set slow roll off vie µC.

Sorry, my post did not take 2 pics.

OK guys, what's the matter. Did I say somthing wrong. Do you sense comercial intrest, or is it something else I have done
that's inappropriate?
I really would like to know how to use a µC to configure this thing.
Someone must know this business.

For the sake of audio

You need a microcontroller, with 3 GPIO lines connected to the CSN/CCLK/CDTI pins of the DAC.

Something small like a Microchip PIC10/PIC12, Atmel ATTiny, etc. should do the job fine. Pick a microcontroller family you know how to use and have programming tools for, and go from there.
